spi_flash: correct documentation on SPI mode
The SPI mode is actually mode3, since the output value is updated on the
falling edge of CLK and the input value is updated on the rising edge.
This also clarifies some of the documentation based on experience with
the core.

failure to meet timing. This facilitates running the build process from a
loop, repeatedly, until a "lucky" p&r solution is found, e.g.:
while true; do

--with-ethernet --yosys-nowidelut \

succeed, regardless of whether timing was met, via '--timing-allow-fail'.
